I'm upgrading CA tools from R17 to R19 and I'm getting a system abend 306 with Reason code= 0C while accessing RC update.
What is the cause.
An 306 - 0C is a
An authorized program requested, by a LINK(X), LOAD, XCTL(X) or ATTACH(X) macro, a module in a non-APF-authorized library or concatenation of libraries.
So given the S306-0C is an authorization problem check all your libraries are correctly APF authorized.
